' Application filed February 20, 1922. Serial No.7537,897.

To aZZw/Lom t may concern.'

Be it known that I, MILTON S. DUNKELT BERGER, a citizen of the United States, residing at Dayton, inthe county of lVlontgomery and State of Ohio, have invented certain new and useful Improvements in Collapsible Baby Carriages, of which the followingl `is a specific-ation.

brtially t0 parallelism with thebediboard ofV the wagon structure.

lapsed thetongue ofV the vehicle kis capable of being turned transversely across the collapsed seat frame and lockedin such po;- sition to retain the .parts in Vcompact relation. When erect, the same locking means is employed to maintain the seat frame in upright adjustment. The seat itself is of the sling type, wherein a length o f fabricl formslthe seat section and also a yielding back, such fabric strip being tensioned by the lerection of the seat frame to afford the necessary resiliency to absorb vibration.

The object of the inventionV is to simplify `1',he\structure as well as the means and mode of adjusting collapsible baby carriages, wherebyithey- Will not onlybe cheapened in construction, but will beV more leflicient in 4use, capable of being easily and quicklyy collapsed t0 a compact form,

and unlikely to get :out of repair.'

provide improved means for securely locking theadjustable parts intheir collapsed condition to afford a compact parcel for shipment orstorage.

frame andparti'c-ularly .an improved resil- Av further ob'ect ofthe inventionis to provide an improved form of mounting for l the draft tongue;

VWith the above primary andother in-` cidental objects in viewV as will more ful-ly appear inthe specification, the invention consists of the features of construction, `the particularly to a collapsible lVhen so colparts Aand combinations thereof, or their equivalents as hereinafter described and set forth in the claims.

Referring to the accompanying drawings, wherein is shown the preferred, but obviously not necessarily the only form of embodiment of the invention, Fig. l is a perspective view of the assembled baby carriage with the seat in its upright or erect position. F ig. 2 is a similar perspective view with the seat part collapsed, and the tongue locked thereacross 1n reverse position. l Fig. 3 is a detail sectional view.

i Like parts are indicated by similar characters of reference throughout the several views.

The carriage or vehicle forming the subjectl matter hereof, comprises a main wagon structureconsisting of the bed board l, supported upon a rear axle or bolster 2, fiXedly secured to thebed board, to which are rotat- .forward end, the bed-board `1 is supported upon afpivoted bolster or axle portion ll, to

which are rotatablysecured the forward carrying` wheels 5. Located on the forward end of the :bed board l, is an upwardly projecting head or boss 6, through which the king pin forming the pivotal connection of the forward axle 4, extends. To the upper end of this king pin there is ixedly connected'a short arm 8, to which Vis hinged the draft tongue A9. The draft tongue 9 is pivoted upon a transverse axis intermediate Vforwardly and upwardly extending fingers u velevated somewhat `above the plane of` the Y A' further object of Vthe inventionis to Y bed board l, and is located forwardly ofthe king pin, `upon the axis of whichthe forward vbolster or axle 4l turns. l

"Mounted upon the bed board 1 is a' foldl .ingr seat frame` comprising a seat back A-ffurther 4object of the inventionis toe4 standard 1l of lsomewhat T-shape. This back standard l1 is hinged at its lower end as at l2 to the bed board l for forwardly and downwardly folding movement. Adjacent to its lower end but in spaced relation Vwith the pivotal connection 12, the yback ably secured rear carrying wheels 3. At the Y kthe occupant.

'forwardly t-heieiirom, with arranged seat rail 1.4. Side ,arms 15 arev pivoted to the extremities oi the T-shaped head oit the back standard, ll, and extend their forward ends pivotallyV connected to the upper' end oi' swinging struts 16, the lower ends oilv which are pivoted to the ends of. the seatrail ll. A. transverse retaining bar li', connects the joints ot the side arins and swinging struts, extending across the seat in front of rllhe seat itself consists oi' a strip 'ot fabric, such as canvas or other strong. but flexible material, which is medially Ylfolded upon itself, and stitched transif'ersely to torni therein ay medi-ally disposed loop 18, which encloses the cross rod 13 of the bach standard ll. The intermediate portion oii'this loopanay be cut away as at i9. to clear the standard ill. This stitching ot the loop 1.8 inedially inthe strip -o't fabric toi-nis thereof' two sections, a seat section il), which extends forwardly from such. loop and has its liorward end secured to the permanently attached seat rail lll, by tacking oiby other means, and a. second upwardly and baclnvai'dly inclined section, attached at its upper end to the cross head 8 of the back standard ll 'l` his upwardly inclined section forms the back of the seat. The ci'oss rod 11.3 ot the back standard being spaced somewhat above the pivotal centerI ot the standard will tendvto move to and fro astheseat is erected or depressed. The seat loop 18 beingE engaged with his cioss arm, the seat section. 2O will be tensioned as the seat frame is adjusted to its upright or erect position. The seat frame is held erect and the section 20 under tension, by any suitable locking means as for instance the hook 22, cai'ried upon the rear end of the bed board l., and ,engaging `i-n a suitable eye in the back standardV ll. By disengaging thisV hook 22, the seat traine may be folded `downwardly and forwardly to substantially parallel rela,

-tion witlithe bed board l as shown in Fig. 2. lllheii so collapsed the `longue is reversed to a position wherein it extends transversely across the collapsed seat Jframe in a tore and aft y direction. as shown in Fig. 2 and is locked in such position by the same locking means or hook 22, which is otherwise eniployed to 'maintain tliefseat in upright ad- `iiistnient The parts are thus securely held f in collapsed condition for shipment or storage. foot board 23 is'pi'etei'ably, though not necessarily provided, in transverse arrangement across-the bedboa-rd l, somewhat in* advance of the seat rail 14;.

I `Frein the above description it will be apparent that there is thus provided adevice f'oythe character described possessing the jfeni'nn'erated as desirable, .but which obV l"particiilar Vfeatures of advantage before viou'sly issusceptible oli-modification in its torms, proportions, detail construction and arrangement of parts without departing from the principle involved or sacrificing any of its advantages.

lllhile in order to'comply with the statute the invent-ion has been described in language more oi' less speciligoas to structural features, it is to be understood that. the invention is notl limited to the specific details shown, but that the means and construction herein disclosed comprises the preferred :torni oli several modes ot putting the invention into effect and the invention is therefore claimed in any oit' its iforms or modifications wit-hin the legitimate and valid scope oi the appended claims. Y

cross rod carried by the back standard in spaced relation with its center of oscilla- Y tion, a sling seat, comprising a strip of p fabric attached to the seat rail at its forward end and 'to the cross rod at its rear said sling seat being tensioned by the erection of the folding back standard, side arms pivoted to the back standard swinging struts pivoted to the seat rail at their .lower ends and pivoted to the side arms at theirupper ends, va transverse rod connecting the arm and strut Joints, the seat strucy ture-being foldable by a forward and ydownward movement substantially to parallelism with the bed board, a tongue capableof being turned transversely across the folded seat structure and locking means engageab'le with the seat when erected and with the tongue when the seat is collapsed to maintain the seat in its position of adjustment. l

6. In a structure of the character described, the combination of a'conveyance structure and a folding seat frame mounted upon the wagon structure, of a strip of fabric folded medially upon itself and stitched in spaced relation with the fold to form an intermediate loop engageable with a movable part of the seat frame, a seat section extending forwardly therefrom and attached at its forward end to a stationary support, a back section extending upwardly and backwardly from the linev of stitch- V ing and attached to a movable part of the seat frame.

In testimony whereof I have hereunto set my hand this th day of January A. D. 1922. Y
